My suggestion is to move the cook top back to the side wall, on the other end of the penninsula. It will save you many steps from sink to stove in your work triangle, and if you have small children it will be in a more protected area, less of a safety hazard. If you keep the cabints over the penninsula, it allows you an easy location for a fan hood. Since I think you are going to do a new countertop anyway, you have a perfect opportunity to tweak your triangle for greater efficiency. Additionally, I'd like to add, yes-to the ceiling, yes-to laminate that looks like granite, (well worth considering), yes-to crown molding, yes-to new back splash, if you decide to paint, I think an ivory kitchen is preferable to stark white. Some of the upper oak doors could have the panel removed and glass, (my suggestion would be ribbed or tuxedo glass) could be inserted.
